B14E0

B14E0-CHANNEL 1 VIDEO CONTINUITY





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

When the ignition switch is in the RUN position, and the radio is in the video mode. The radio sends a video signal to the Video Screen Module, using circuits (X534) video 1 signal , (X535) video 1 common and (X536) video 1 shield, which displays on the video screen.

- When Monitored:
Ignition on, and the radio is in the video mode.

- Set Condition:
No video is displayed on the rear video screen.





1. CHECK FOR AN INTERMITTENT CONDITION
1. Turn the ignition on.
2. Set the radio in the video mode.
3. With the scan tool, record and erase the radio DTCs.
4. Cycle the ignition switch from on to off, wait five seconds and then back to on.
5. Turn the ignition on and set the radio in the video mode.
6. With the scan tool, read the active radio DTCs.

Does the scan tool display active: B14E0-CHANNEL 1 VIDEO CONTINUITY?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE (X534) VIDEO 1 SIGNAL, THE (X535) COMMON, AND THE (X536) SHIELD CIRCUITS FOR AN OPEN CIRCUIT




1. Disconnect the radio C3 harness connector.
2. Disconnect the Video Screen Module C1 harness connector.
3. Measure the resistance of the (X534) (X535) and (X536) circuits between the Video Screen Module harness connector and radio C3 harness connector.

Is the resistance below 5.0 Ohms on the (X534) (X535) or (X536) circuits?

Yes

- Replace the radio. Radio - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the appropriate circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
